A light microscope comprises a light source (10) for illuminating a specimen (35), a sensor array (60) comprised of photon-counting detector elements (61, 62) for measuring detection light (15) coming from the specimen (35), and a control device (70) for controlling the sensor array (60). The control device (70) is configured for flexibly binning the photon-counting detector elements (62) into one or more super- pixels (65).
